NEW YORK/LONDON, Nov 5 (Reuters) - Gold dropped more than 2 percent Wednesday as oil tumbled and Barack Obama's historic White House victory bolstered the dollar, which pressured commodities across the board.
"The dollar is pretty strong and the (gold) decline was on the back of oil. This is just more of the same people who don't believe right now gold can rally," said Bruce Dunn, vice president of trading at New Jersey-based Auramet Trading.
Dunn also cited a thin market and "sell the rally" mentality among bullion investors.
Spot gold <XAU=> was at $741.30, down 2.6 percent from Tuesday's close of $761.95.
U.S. December futures <GCZ8> settled down $14.90, or 2 percent, at $742.40 an ounce on the COMEX division of the New York Mercantile Exchange.
Fresh strength in the dollar on Wednesday has pressured gold. The dollar rose against a basket of currencies after Obama's victory, and as traders weighed up the prospect of a euro zone rate cut later this week. [
]The European Central Bank is expected to cut interest rates by 50 basis points at a meeting on Thursday.
Gold's other main external driver, crude oil, was also sharply weaker, ending more than $5 a barrel lower to below $66 after a U.S. government report showed rising fuel stockpiles.
However, strong physical demand for gold and a better appetite from buyers after it held at the $700 an ounce support level are likely to underpin prices, traders said.
Also, Venezuela said it will take over Canadian miner Crystallex's <KRY.TO> Las Cristinas gold project, one of Latin America's largest, the latest move by President Hugo Chavez to bring key industries into the hands of the state. [
]George Gero, vice president of RBC Capital Markets Global Futures, said that the gold market tended to ignore geopolitical problems and political fears such as the Venezuela news.
Gero cited hedge fund liquidations triggered by the sharp drop in the U.S. stock markets. The broad-based Standard & Poor's 500 index <.SPX> was down more than 4 percent in late trading.
PLATINUM FIRMS
Among the other precious metals, platinum <XPT=> ended at $863.50, up 2.6 percent from its Tuesday close.
Anglo Platinum <AMSJ.J>, the world's biggest producer of the white metal, said it had shut down its Polokwane smelter in South Africa after a furnace run-out earlier in the day.
It said the shutdown would result in a 150,000-200,000 ounce reduction in its refined platinum output for 2008. [
]Sister metal palladium <XPD=> was at $215.00, up 4.1 percent from Tuesday's close. Both metals have fallen sharply in recent months on falling demand from carmakers.
Rhodium slid to a near four-year low, also on weak auto market demand. Like platinum and palladium, rhodium is chiefly used as a component in autocatalysts.
Rhodium <RHOD-LON> slipped to $1,400 an ounce, from a previous quote of $1,595. It has shed more than 85 percent of its value since touching a high above $10,000 an ounce in June.
Silver <XAG=> closed at $10.43, up 2.6 percent from Tuesday's close. (Editing by Jim Marshall)
